Industrial Thanksgiving: Science Takes Mom’s Recipes to the Assembly-Line


From Wired Science:

Thanksgiving is about eating, and though local, organic food might be what the cool kids are eating, most people are still eating products of the industrial food system.

Whether you’re talking turkey, cranberries or potatoes, industrial-scale processes have been developed to drive down food costs, drive up corporate profits and feed America’s incredible hunger for novel food items.

But most consumers of these manufactured meals have little or no knowledge of the machines and methods used to freeze turkeys, turn potatoes into fake potatoes, and cranberries into TV-dinner cranberry sauce. It’s not always pretty, but food scientists’ epic battle to scale up your mom’s recipes without making them taste nasty is worth examining, if not giving thanks for.

Thanksgiving Day Facts: Pilgrims, Dinner, Parades, More

From National Geographic:

It may be called Turkey Day, but the U.S. Thanksgiving Day is about more than just the bird. Learn about a holiday myth—the first "real" Thanksgiving wasn't until the 1800s—and how we celebrate Thanksgiving dinner today.

Key to any Thanksgiving Day menu is a fat turkey and cranberry sauce.

Some 250 million turkeys were raised in the U.S. in 2009 for slaughter, according to the U.S. Department of Agriculture's National Agricultural Statistics Service. Those birds were worth about U.S. $4.5 billion.

Chandra Hosts A Carnival Of Space



From the Chandra Blog:

This week, the United States marks the Thanksgiving holiday. For most of us, this means lots of time with family (sometimes too much), friends, and vast amounts of food. It also causes all productivity to cease anywhere close to Thursday and the days that follow. That said, however, science and space never sleep – not even from an overdose of tryptophan. (For those of you who are unfamiliar with this word, it has to do with pseudo-urban legends surrounding the American overconsumption of turkey on this holiday.) Now, off to our spin around the blogs.

From Technology Review:

Researchers are working to treat pandemic flu by recruiting a patient's own immune cells.

Viruses multiply incredibly quickly once they've infected their victim--so fast that antiviral medications such as Tamiflu are only effective if given during the first few days of an infection. After that, the viral load is just too high for a single drug to fight off. But researchers are working on a treatment for the H1N1 virus (or swine flu) that uses a different approach. Rather than disabling the virus with a drug, they're creating a vaccine that can activate and steer a patient's own immune cells to attack the invader.

Shuttle Atlantis Departs From Space Station



From Space.com:

The space shuttle Atlantis cast off from the International Space Station early Wednesday after almost a week linked to deliver vital spare parts.

The shuttle detached from the orbiting laboratory at 4:53 a.m. EST (0953 GMT), and flew in a circle around the station so that astronauts on the orbiter could snap detailed photographs to check on the state of the outpost.

"It's a pretty exciting thing to do, be able to see the station you were living in again now on the farewell," STS-129 commander Charlie Hobaugh said in a preflight interview. "Just having it gives us a new snapshot in time of the condition of the vehicle at that point."

Organic Wine-Makers Look to Greener Packaging

There are no bottles in these boxes of wine -- just wine and the plastic pouch that holds it. Boxing instead of bottling wine saves half the shipping weight (and associated carbon emissions) and keeps the product fresher longer. Bota Box

From Scientific American:

More and more wineries offer organic varieties to lower their eco-footprints. It's no surprise that they're looking at their product packaging's environmental impacts, as well.

With more and more wineries offering organic varieties to lower their eco-footprint, it’s no surprise that they’re looking at the environmental impacts of their packaging as well. The making of conventional glass bottles (and the corks that cap them) uses significant quantities of natural resources and generates considerable pollution. According to the U.S. Environmental Protection Agency, the process of manufacturing glass not only contributes its share of greenhouse gas emissions but also generates nitrogen oxides, sulfur dioxide and tiny particulates that can damage lung tissue when breathed in.
